Please someone help me here it is doing my head in.
I have 2 1pc cranks, a tagagi mx (T7.81) and a mongoose (T165, 24), I have purchased to BB's from ebay a 24tpi & 28tpi and I cannot get any of them to go on either crank. I have tightened as far as I can and am still left with approx 1/2cm gap so the the chainwheel just wobbles about. What am I doing wrong??? Could they be duff BB's?
